As a general rule any time we switch() on something that is an enum, we
want to have a case for every enum constant. The -Wswitch warning will
report any switch where we've violated this rule, except if that switch
has a default case.
Unfortunately it is reasonable to want to list all enum constants *and*
also have a default case. To get a warning in that scenario requires
that we turn on -Wswitch-enum.
In a few cases where we explicitly don't want to list all enum cases, we
can discard the enum type checking by casting the value to a plain int.

Undefined symbols are a bad thing in general because they can get
resolved in unexpected ways at runtime if multiple sources provide the
same symbol name. For example both glibc and libtirpc may provide XDR
symbols and we want to ensure that we resolve to libtirpc if that's what
we originally built against.
The toolchain maintainers thus strongly recommend that all applications
use the '-z defs' linker flag to prevent undefined symbols. This is
shortly becoming part of the default linker flags for RPMs. As an added
benefit this aligns Linux builds with Windows builds, where the linker
has never permitted undefined symbols.

back to json using libxl_domain_config_to_json(). The two json
docs are then compared.

Implement a new libssh transport, which uses libssh to communicate with

This new transport supports all the common ssh authentication methods,
making use of libvirt's auth callbacks for interaction with the user.
${exec_prefix} and ${prefix} point to the same directory in
most setups, but when that's not the case the former should
be used for architecture-dependent data such as shared objects,
which makes it the best fit for our Wireshark dissector.
While at it, change all uses of $(var) to ${var}: they are
absolutely identicaly as far as make's concerned, but autoconf
itself seems to prefer the latter form so we might as well
follow suit.
We only need to strip $ws_prefix from $ws_plugindir if we've

from $libdir, we can just use it without further processing.

Since we're using autoconf to substitute the right value in
Makefile.am now, we can use a less generic name without running
into circular dependencies.
Adding $(prefix) in Makefile.am, as we were doing, means that
it would be prepended even when using --with-ws-plugindir,
which is something we don't want to happen.
Instead, we add it beforehand but take care that it doesn't
get expanded until make is called.
Even when we're building $plugindir ourselves because we can't
retrieve it using pkg-config, we still want to strip the prefix,
except in that case it would be the same prefix we're using for
building libvirt.
The fact that $plugindir is missing also doesn't tell us
anything about $ws_prefix, so we have to handle the two variables
separately.
Running the output of qemu -help doesn't make any sense. We should be
looking for libvirt being mentioned in the output. This worked by

functions in sanlock library as the sanlock_write_lockspace was
introduced in 2.7 release and the one we are currently checking
for in the 2.5 release. Therefore it is safe to assume presence

has finished starting up. All it does is send a datagram
containing the string parameter to systemd on a UNIX socket
named in the NOTIFY_SOCKET environment variable. Rather than
pulling in the systemd libraries for this, just code the
notification directly in libvirt as this is a stable ABI
from systemd's POV which explicitly allows independant
implementations:

We don't need them any longer; moreover, the previous structure
made it very easy for bugs to slip in, by having the result of one
check influence the following one.
By placing the check for "$with_init_script" = check front and
center, hopefully this won't happen (as easily) again.
Our distcheck is broken. Well, it works but only by pure chance.
When wireshark plugin is enabled, we try to query which path
should the plugin be installed into. Firstly, we try to ask
pkg-config as some releases of wireshark already sets
corresponding variable in their pkg-config files. However, if we
obtained no value from there we try to construct the path on our
own. Based on our observations it usually is:
$libdir/wireshark/plugins/$version/.
Now, the problem is in the way we are deciding whether we have
obtained the plugin directory from pkg-config or not. Simply
said, we are checking wrong variable. The variable we are
checking has never been set, thus in our test is empty and
therefore we will always construct the plugin dir path on our
own, regardless of its presence in the pkg-config file.
To make things worse, after fixing this problem, VPATH build was
broken as it now tried to install plugin into correct directory.
Yes, this is problem, because --prefix was not honoured and
everything but the plugin was installed into given prefix. I've
managed to resolve this issue by replacing plugin dir prefix with
our own. So when doing regular installation (our prefix ==
wireshark prefix), nothing changes. When doing VPATH build &
installation plugin is installed into correctly prefixed dir.

The check is supposed to stop users from trying to compile
virt-login-shell on Windows by erroring out during the
configure phase; however, there are two flaws in it:
* the value of "x$with_win" is compared to "yes" instead
of "xyes" (note the "x" in the first string)
* "test" is not being used, so the script will actually
try to run a command called "x$with_win" instead of
performing string comparison
This patch fixes both issues.

Name Service Switch is a glibc feature responsible for many
things. Translating domain names into IP addresses and vice versa
is just one of them. However, currently it's the only
functionality that this commit is tickling. Well, in this commit
the plugin skeleton is introduced. Implementation to come in next
patches.
Because of the future testing, where the implementation is to be
linked with a test, this needs to go into static library. Linking
a program with an .so statically is not portable. Therefore a
dummy libnss_libvirt_impl library is being introduced too.

There has been a report on the list [1] that we are not
installing the wireshark dissector into the correct plugin
directory. And in fact we are not. The problem is, the plugin
directory path is constructed at compile time. However, it's
dependent on the wireshark version, e.g.
/usr/lib/wireshark/plugins/1.12.6
This is rather unfortunate, because if libvirt RPMs were built
with one version, but installed on a system with newer one, the
plugins are not really loaded. This problem lead fedora packagers
to unify plugin path to:
/usr/lib/wireshark/plugins/
Cool! But this was enabled just in wireshark-1.12.6-4. Therefore,
we must require at least that version.
And while at it, on some distributions, the wireshark.pc file
already has a variable that defines where plugin dir is. Use that
if possible.

Systemd does not forget about the cases, where client service needs to
wait for daemon service to initialize and start accepting new clients.
Setting a dependency in client is not enough as systemd doesn't know
when the daemon has initialized itself and started accepting new
clients. However, it offers a mechanism to solve this. The daemon needs
to call a special systemd function by which the daemon tells "I'm ready
to accept new clients". This is exactly what we need with
libvirtd-guests (client) and libvirtd (daemon). So now, with this
change, libvirt-guests.service is invoked not any sooner than
libvirtd.service calls the systemd notify function.

At this point it has a limited functionality and is highly
experimental. Supported domain operations are:
* define
* start
* destroy
* dumpxml
* dominfo
It's only possible to have only one disk device and only one
network, which should be of type bridge.
We support gluster volumes in domain XML, so we also ought to
support them as a storage pool. Besides, a future patch will
want to take advantage of libgfapi to handle the case of a
gluster device holding qcow2 rather than raw storage, and for
that to work, we need a storage backend that can read gluster
storage volume contents. This sets up the framework.
Note that the new pool is named 'gluster' to match a
<disk type='network'><source protocol='gluster'> image source
already supported in a <domain>; it does NOT match the
<pool type='netfs'><source><target type='glusterfs'>,
since that uses a FUSE mount to a local file name rather than
a network name.
This and subsequent patches have been tested against glusterfs
3.4.1 (available on Fedora 19); there are likely bugs in older
versions that may prevent decent use of gfapi, so this patch
enforces the minimum version tested. A future patch may lower
the minimum. On the other hand, I hit at least two bugs in
3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth
raising the minimum: glfs_readdir is nicer to use than
glfs_readdir_r [1], and glfs_fini should only return failure on
an actual failure [2].
